Many such places, at least where I'm from, center around power plants or are located on government property. There are reservoirs close by that legend says are loaded with trophies. But get caught there and you're greeted with an assault rifle. On a lesser scale, there is a lake I know ringed with houses. I never see anyone fishing it, and though I've studied maps, there is no public access. Maybe one day I'll start knocking on doors, though I doubt I'll get a free pass from anyone.
